Question 3 of 30

Mathematics
1 answer:
nadezda [96]3 years ago
5 0

Answer:

(C) 10.4 lb

Step-by-step explanation:

If Paul added each weight before adding, as you state, he got:

Apples     3.78 ⟶  3.8

Peaches   2.12 ⟶  2.1

Oranges  4.45 ⟶ <u> 4.4 </u>

                    Total 10.3 lb

If he did it this way, he did it <em>incorrectly</em>, and his answer isn't in the list of options, anyway. That's because his method introduces round-off errors.

The correct way is to add the numbers as given, and then round off <em>at the end</em>.

Apples     3.78

Peaches  2.12

Oranges <u> 4.45</u>

   Total  10.35 ⟶ 10.4 lb

Note: When you drop a 5 f<em>ollowed by nothing</em>, you round off to the <em>nearest even number</em>.

A square has a side length of (2x + 4) inches.
Oksi-84 [34.3K]

Answer:

The answer is C, E and F .

Step-by-step explanation:

Given that the area of square is, Area = length×width. In a square, all sides are equal so you have to substitute (2x+4) into the formula :

Let length be (2x+4) inches,

Let width be (2x+4) inches,

Area = (2x+4)(2x+4)

= (2x+4)² (option C)

= 4x² + 16x + 16 (option F)

= 4(x² + 4x + 4) (<em> </em><em>F</em><em>a</em><em>c</em><em>t</em><em>o</em><em>r</em><em>i</em><em>z</em><em>e</em><em> </em>)

= 4(x+2)² (option E)

You can use the formula, (a+b)² = a² + 2ab + b² to evaluate quickly.

Think I know this but need an expert to help
erma4kov [3.2K]

Answer:

2.625 kg

Step-by-step explanation:

875 g of flour makes 32 slices (8 bases x 4 slices each)

24 bases (3 times the recipe) makes 96 slices (which is between 90-100)

3 times 857 g = 2625 g

answer is looking for kg so 2625 g is equal to 2.625 kg

So 2.625 kg of flour would make 24 bases which is 96 slices.
